Abstract

The invention relates to a polymer-based cerium-doped nano zinc oxide compound antibacterial agent for fabric and a preparation method thereof. The preparation method includes using cerium nitrate and zinc acetate as raw materials, preparing rare-earth cerium-doped nano zinc oxide through the coprecipitation method; using the cerium-doped nano zinc oxide, dimethyldiallylammonium chloride, and allyl glycidyl ether as raw materials, preparing the polymer-based cerium-doped nano zinc oxide compound antibacterial agent through the in-situ method, introducing the cerium-doped nano zinc oxide into the polymer base containing positive ions and the epoxy group. The polymer-based cerium-doped nano zinc oxide compound antibacterial agent for fabric is used for antibacterial arrangement of cotton fabric, antibacterial broad spectrum of the antibacterial agent is broadened through the synergic action of quaternary ammonium salt and the doped zinc oxide, and long effect of the antibacterial agent can be kept by means of the epoxy group and the hydroxyl action of the cotton fabric. Meanwhile, the preparation method of the compound antibacterial agent is simple, environment friendly, nontoxic and harmless for humans.

Description

technical field [0001] The invention belongs to the technical field of fabric antibacterial agents, in particular to a polymer-based cerium-doped nano zinc oxide composite antibacterial agent for fabrics and a preparation method thereof. Background technique [0002] Cotton fabric is very popular because of its good air permeability and comfort. However, this kind of cellulose fiber is easy to breed bacteria and other microorganisms, which will make the textile discolored and yellow, produce unpleasant smell, and even cause cross-infection to endanger human health. . Therefore, it is particularly important to carry out antibacterial finishing to textiles, and a large number of demands have promoted the research and development of antibacterial finishing agents for fabrics. [0003] Nano-zinc oxide is a popular inorganic antibacterial material in recent years. It has the characteristics of small size, large specific surface area and high stability. It has excellent antibacte...
